Stormy Daniels claims she saved a dress she wore during a sexual encounter with Donald Trump and now plans to get it tested for his DNA.

Celebrity gossip site The Blast, which first broke news that Daniels planned to break her silence on her affair with Trump, now claims that the porn actress is in possession of a “Monica Lewinsky dress” that she will use as proof of her claims of her affair with the president.

“Sources close to Daniels tell The Blast the shimmering gold mini dress with a plunging neckline was kept in pristine condition after her alleged 2006 sexual encounter with Trump at the Lake Tahoe hotel suite,” the publication writes. “We’re told Daniels is planning on having the dress forensically tested to search for any DNA that proves she isn’t lying about her tryst with Trump, including samples of skin, hair or… anything.”

However proving it has Trump’s DNA on it would require Trump to submit some of his own DNA so it could be compared to any DNA found in the dress.

The article notes that “any DNA that may be extracted from her dress that could possibly prove Trump was with her in the hotel room will be a big deal.”
